When setting up a multiple testimonials widget, you have a range of settings for the grid layout:
Grid layout settings page exampleColumns and rows
Choose how many testimonials you'd like to display in your grid by specifying a number of columns and rows. The grid will be fully responsive, meaning that on a mobile device a 3-column grid will adjust to a single column.
Fixed height boxes
Select this option to set a uniform height to all of the testimonials within a row.
